根据团头鲂鱼种营养需要，用商品饲料原料和维生素、矿物盐等添加剂组成营养平衡的试验基础日粮。从基础日粮中分别去除添加的无机磷、锌和复合多维便构成了本次试验的三种试验日粮。试验鱼平均体重８．４３ｇ。４０天的网箱养殖试验表明，当从基础日粮中分别去除添加的无机磷、锌和复合多维后，团头鲂鱼种生长速度和饲料利用率均显著下降（Ｐ＜０．０５）。采食基础日粮、去除无机磷日粮、去除锌日粮和去除复合多维日粮的鱼，其平均增重率分别为１４７．６７％、１０８．４７％、１０６．７５％和１１６．７５％
According to the nutritional needs of the bream fish species, with commercial feed ingredients and vitamins, mineral salts and other additives to form a nutritional balance of the experimental basis of diet. From the basic diet were added to remove the inorganic phosphorus, zinc and composite multi-dimensional will constitute the test of the three test diets. Test fish average body weight 8.43g. The 40-day cage culture experiment showed that the growth rate and feed utilization rate of the minnows were significantly decreased (P <0.05) after removing the added inorganic phosphorus, zinc and composite multidimensional from the basal diet respectively. The average rate of weight gain of basal diet, inorganic phosphorus diet, zinc diet and composite multidimensional diet were 147.67%, 108.47%, 106.75% and 116.75, respectively %
